I have Hitachis that are 2 years old running in raid 10 (MD) with no issues. An other array have had 1 WD black go bad. I have one array that I mixed drive brands (each 1.TB) w 1 Seagate Barracuda in the array (raid 10). The Seagate always falls out of sync due to virtual blocking.
I'm trying WD reds next.
Credible - hmmm - all I have is the vendor's assertion the drives were new from Seagate. Times two vendors.
For you WD fans out there - I just had 4 WD Enterprise drives fail on me in the past month (out of 18 in two arrays). They were all dated Nov 2010 - that should give you an indication how long they last under 24x7x365 use in a data center.

If you have credible evidence that Seagate is selling used Hitachi drives as new and under their label I'm sure your State Attorney General would like to hear from you.

How many [thousand] hours on the drive? I think you're gambling if---------------------------------------------------
you have more than 26,000 hours (3 years) and ESPECIALLY if it's
really a Hitachi drive. Seagate bought Hitachi recently, and from
what I've seen, are selling used Hitachi drives as "new" Seagate
drives - check the model number and the run hours!
Hard drives are killing me this year - I've spent over 80 hours in
rework because of failed drives - especially with Seatachi drives (see
above). 80 hours of rework at no pay is a painful lesson.

Greetings!
I have a 500GB Seagate ST3500312CS SATA drive salvaged from a decommissioned DVR. The DVR's OS said SMART status OK. The latest Seatools disk utility from the Seagate website says the drive is A-OK (short test, long test, full erase, re-test) no errors found.
However, the Gnome disk utility in Mint 17 says 'Threshold not exceeded' and 'Disk is OK, 178 bad sectors'.
Some other SMART attributes displayed:
ID1 Read Error Rate: 152141757
ID5 Reallocated Sector Count: 178 sectors
ID187 Reported Uncorrectable Errors: 0 sectors
ID198 Uncorrectable Sector Count: 0 sectors
ID199 UDMA CRC Error Rate: 0
GSmart Control 0.8.7 is reading the same thing, 178 sectors, but also says it's OK.
running an e2fsck from gparted reports 0 bad blocks.
I've also retested in another machine with different cables to minimize the possibility of bogus hardware or BIOS issues, but the results remain the same.
Seagate's website has a FAQ that says their tools should be the final say as they're designed to work correctly with their drives.
Normally a bad sector or two wouldn't bother me, I have drives that have been running for years like that. I just keep backups fresh and check for bad sector growth. A few bad sectors is within spec and that's why HDD's have a reserved area. Yet somehow 178 sectors seems like a lot.
Should I trust this drive for anything more than a paperweight?
Should I trust anything with the words 'smart', 'affordable', or 'free' in the name? ;]
Thanks!
